Abstract
A molecular species is covalently attached to elemental carbon by exposing the carbon to a reaction mixture containing a strong base and a compound of the formula (I) or (II) in which X denotes a covalently attached atom or group capable of forming an X− anion and each Z is a moiety comprising a plurality of atoms, but which does not have a hydrogen atom directly attached to the atom which itself is directly attached to the —CH2X or —CHX group. The carbon substrate may be graphite or carbon nanotubes.

A process for attaching molecules to elemental carbon comprising exposing a carbon substrate to an aprotic reaction mixture containing a base and a compound with a general formula
- or
- Z—CH2X
- in which X denotes a covalently attached atom or group capable of forming an X− anion and each Z is a covalently attached moiety comprising a plurality of atoms, which remains attached and does not have a hydrogen atom directly attached to the atom which itself is directly attached to the —CH2X or —CHX group.
